Sabatieria conicauda Vitiello, 1970 (ref. ID; 1902, 3571)

Descriptions

  • Female: Females are similar to the males in general body shape, anterior sensilla and cuticular punctations. The reproductive system is amphidelphic with outstretched ovaries. There is a spermatheca on each branch that may be filled with sperm cells. The vulva is simple and the vagina is short. The tail shape is similar to that of the males for most females; it is 52-75 µm long (tail length divided by anal body diameter=2.0-3.1); in some females a more conical tail is present. (ref. ID; 1902)
  • Male: Body is cylindrical; anterior end broad and tail is short conico-cylindrical. The head measures 10-12 µm in diameter and it is slightly set off from the rest of the body. The cuticle is punctated; laterally, the dots are larger and irregular and more widely spaced. There are eight rows of somatic setae; these are eight rows of somatic setae; these are longer (3 µm) at the pharyngeal and the tail region than on the rest of the body (1.5 µm). The outer and inner labial sensilla are short; the cephalic ones are setiform 3-4 µm long (25-40%). The amphids are multispiral with three turns, 7-9 µm in diameter (62-64% corresponding body diameter) and they are located posterior of the cephalic setae. The stoma is cup-shaped in the anterior part and narrow tubular in the posterior part which is surrounded by the pharyngeal muscles. The pharynx is cylindrical, 139-163 µm and has a swollen posterior end that forms an elongate terminal bulb, 17-24 µm wide. The corresponding body diameter at that level of the bulb is 23-31 µm. The nerve ring surrounds the pharynx at 74-87 µm from the anterior. The opening of the ventral gland is found posterior of the nerve ring at 95-105 µm from the anterior. The ventral gland is located at the pharyngo-intestinal junction. The ventral gland is located at the pharyngo-intestinal junction. The cardia is short and pear-shaped. The reproductive system is diorchic, with opposed and outstretched testes. The anterior branch is to the left and the posterior to the right of the intestine. The sperms are oval to elongate and appear striated. The spicules are 1.3-1.5 anal body diameter long, slightly curved and without a capitulum. The gubernaculum is short with a straight dorso-caudal apophysis 8-12 µm long. There are nine fine ventral pre-cloacal supplements extending anteriorly from the cloaca to about 119 µm. The tail is conico-cylindrical, 54-76 µm long (tail length divided by anal body diameter 2.5-2.8). There are two terminal setae. The caudal glands open through a spinneret at the terminal end. (ref. ID; 1902)

    Sabatieria lucia Muthumbi, Soetaert & Vincx, 1997 (ref. ID; 1902 original paper)

    Diagnosis

    Sabatieria lucia sp. n. is characterised by short but distinct inner labial, setiform outer labial (2 µm long) and cephalic sensilla (4-5 µm long or 30-33% corresponding body diameter); amphideal fovea are 2.75 turns or 73-80% corresponding body diameter and slightly curved spicules that have a poorly developed capitulum (52-57 µm long). S. lucia sp. n. resembles S. paradoxa Wieser and Hopper, 1967, S. paracupida Wieser and Hopper, 1967, S. preadatrix Schuurmans Stekhoven, 1950 and S. stekhoveni Vitiellio, 1970 because of the shape of the head and tail and the cuticular punctations. S. lucia sp. n. can be distinguished from these species by the length of the outer labial sensilla, which are distinct but very short in all these species, and cephalic sensilla which are longer in these species than they are in S. lucia sp. n.; cephalic setae are 6-7 µm in S. paradoxa, 10 µm in S. paracupida, 5-6 or 50-57% corresponding body diameter in S. stehoveni and 54% corresponding body diameter in S. preadatrix. S. lucia sp. n. can also be distinguished from these species by the length of the spicules; they are 60-63 µm in S. paradoxa, 60-68 µm in S. paracupida, 63-69 µm in S. preadatrix and 44-47 µm in S. stekhoveni although S. stekhoveni is longer (body length 1400-1817 µm) than S. lucia sp. n. (ref. ID; 1902)

    Descriptions

  • Female: The females are similar to the males in general body shape, anterior sensilla and cuticle. The ventral gland is located at the pharyngeal-intestinal junction. The ovaries and the uterus could not be seen clearly; vulva is located at 47% from the anterior. The tail is similar to that of the males but it is slightly longer (142 µm) and the anal body diameter smaller (28 µm). (ref. ID; 1902)
  • Male: Body is cylindrical, broad and rounded anteriorly and conical with a cylindrical tail end. The head is slightly offset and it measures 14-16 µm in diameter. The cuticle is punctated and annulated. Punctations begin from the anterior edge of the amphids, just posterior of the cephalic setae. Laterally, the punctations are larger and more widely spaced, on the rest of the body, they are smaller and arranged in transverse rows. Annulations are conspicuous at the tail region. There are eight longitudinal rows of somatic setae; these are longer at the pharyngeal and the tail region than at the rest of the body where they become inconspicuous. Anterior sensilla are in three separate crowns with inner and outer labial sensilla short but setiform (2 µm) and the four cephalic sensilla are 4-5 µm long (30-33% head diameter at the level of the cephalic setae). The amphids are spiral with 2.75 turns; they are 9-13 µm wide (73-80% corresponding body diameter) and located immediately posterior of the cephalic setae. The stoma has a cup shaped anterior part and a conical posterior part; the pharyngeal muscles surround the posterior part of the stoma. The pharynx is cylindrical, 178-211 µm long, and slightly swollen to form a bulb. The marginal tubes start from the base of the stoma until the bulb and they are lined with thick cuticle. The canal of the dorsal pharyngeal gland opens at the base of the stoma. The ventral gland is located posterior the pharyngeal-intestinal junction and it opens through an ampulla at 50-61% of the pharyngeal length from the anterior. The nerve ring is located at 44-51% of the pharynx from the anterior. Cardia is short but prominent. The reproductive system is diorchic, with opposed and outstretched testis. The anterior branch is to the left and posterior the right of the intestine. The sperm cells are large, elongate to oval shaped and have a clear nucleus and a dark nucleolus. The spicules are slightly curved, without capitulum; they are 1.5-1.8 anal body diameter long. There are three to four pairs of copulatory glands located anterior of the spicules and other glandular cells without clear nucleus at the vicinity of the spicules. The gubernaculum is short with a long caudal apophysis (that may vary in length from one specimen to the other). One ventral pre-cloacal seta and 12 tubular supplements. The tail is conical with posterior half cylindrical and a swollen tip, 118-136 µm long (tail length divided by anal body diameter 3.5-3.9). Three setae at the tail tip. The three caudal glands open through a prominent spinneret at the tail tip. (ref. ID; 1902)

    Etymology

    The species is named after Dr. Lucy Irungu of University of Nairobi. (ref. ID; 1902)

    Sabatieria pisinna Vitiello, 1970 (ref. ID; 1902, 3571)

    Descriptions

  • Cylindrical nematodes: attenuated towards the anterior (30-40% of maximal body width); tail with short cylindrical endpart. Cuticle transversely punctated from level posterior tot the cephalic setae to the tail tip; lateral differentiation consists of rows of larger dots, each row corresponding with one row of smaller an more closely spaced dots dorsally and ventrally. Somatic setae very short, in eight rows; epidermal glands associated with these setae visible as oval, bright spots. Internal and external labial sensilla short, in two separate rows; a third crown of cephalic setae (3 µm. i.e., 25-30% of corresponding head diameter) is 4-5 µm from the anterior end. Amphideal fovea multispiral, ventrally wound, anterior border 5-6 µm from the anterior end; in males 3.25-3.5 turns, 9-10 µm wide (75% corresponding body diameter); in females 2.75-3.25 turns, 8-9 µm wide (60-70% corresponding body diameter). Buccal cavity conical in anterior, narrow in posterior part, small projections are at the border between the two compartments. (ref. ID; 1902)
  • Pharynx cylindrical, posteriorly enlarged: marginal tubes obvious; two ventrosublateral and one mediodorsal pharyngeal gland distinct, the former emptying posterior to the level of the excretory pore, the latter in anterior most part of pharyngeal lumen. Cardia 4 µm long. Intestinal cells with refractive granules. Nerve ring at 55% of pharyngeal length. Ventral gland posterior to the cardia; excretory pore posterior to the nerve ring; accessory gland in males not obvious. (ref. ID; 1902)
  • Male diorchic: testes outstretched and opposite; anterior testis left of the intestine, posterior testis smaller, right of the intestine. Spermatozoa globular. Vas deferens differentiated: anterior and posterior part with refractive granules, small central part much brighter, almost empty. Two to four ejaculatory glands are on both lateral sides of the vas deferens in tandem position, each gland with its own outlet, emptying in the cloacal region. Two equal spicules, slightly bent; central lamella in two parts: distal part in anterior third of spicules, proximal part in posterior 2/3, the latter part distally sometimes connect with the ventral margin of the spicule. Gubernaculum with two curved, dorsocaudally directed apophyses (8-10 µm); cuneus with curved shape; ventrally are two lateral expansions of the gubernaculum and an anterior bar, thus surrounding the spicules completely. One precloacal ventral seta. Precloacal supplements not seen. (ref. ID; 1902)
  • Female didelphic, amphidelphic: ovaries outstretched; anterior ovary left, posterior one right of the intestine. Two spermathecae present. In one female, apart from a well developed posterior ovary (with one large oocyte), two anterior ovaries were observed, one right, the other one left of the intestine, both with a well developed but somewhat flattened oocyte; only in the branch on the left of the intestine is a spermatheca present. Tail conical in anterior 2/3; posterior third cylindrical; three subterminal setae; three caudal glands entirely in tail region. (ref. ID; 1902)
